PRIOR ARTS

In countries of Europe and America, cardiovascular diseases head the list of death causes. In Japan, although cerebrovascular diseases such as cerebral apoplexy ranked high in the list of the death causes, ischemic heart disease has prominently increased recently, as the life-style and eating habit of Japanese have neared those of European and American.

Ischemic heart disease generally refers to a series of heart diseases caused when the supply of oxygen to cardiac muscle cannot make up for myocardial oxygen consumption. Representative examples thereof include coronary sclerosis, acute cardiac infarction and angina pectoris. Although nitro drugs, calcium antagonists and β-blockers are now generally used for the treatment of these diseases, no decisively effective drug has been found as yet, so that it is highly expected to develop a novel drug more excellent than those of the prior art.

Experimental Example 2 Heart Rate Lowering and Coronary Bloodflow Increasing Effects Upon Anesthetized Thoracotomized Dog

The chest of a grown-up mongrel was opened under enflurane inhalation anesthesia. The blood flow of the coronary artery was determined by setting a probe of an electromagnetic bloodflowmeter at its left circumflexbranch, while the heart rate was determined by triggering the wave form of the pressure in its left ventricle and counting it with a tachometer.

The intravenous administration of a test compound (in a dose of 0.3 mg per kg of the weight of the anesthetized mongrel) was carried out by using a catheter inserted into its femoral artery.

The effect of increasing the bloodflow of the circumflex branch of the left coronary artery or the heart rate lowering effect was evaluated based on the difference between the bloodflow or the heart rate after the administration and that before the administration according to the following criteria. The results are shown in Table 2 by a symbol (+).

EXAMPLES OF THE COMPOUND I Preparative Example 1 4-(4-Methyl-1H-imidazol-1-yl)benzaldehyde ##STR53##

4.20 g of sodium hydride (a 60% suspension thereof in a mineral oil) was suspended in 150 ml of dimethylformamide to obtain a suspension. 8.62 g of 4-methylimidazol was added to the suspension at a room temperature under stirring in portions. After one hour, 12.4 g of 4-fluorobenzaldehyde was added to the obtained mixture. The obtained mixture was stirred for 4 hours and poured into ice-water. The obtained mixture was extracted with chloroform. The extract was dried over anhydrous sodium sulfate and distilled under a reduced pressure to remove the solvent. The obtained residue was purified by silica gel column chromatography (solvent: chloroform/methanol (50:1)) to obtain a solid product. This solid product was washed with ether to obtain 2.67 g of the title compound as a pale yellow powder (yield: 14%).

Preparative Example 3 4-(4-Pyridyl)benzaldehyde ##STR56##

A solution of 6.93 g of 4-bromobenzaldehyde dimethyl acetal in 40 ml of tetrahydrofuran was dropwise added to a mixture comprising 0.80 g of magnesium powder, a catalytic amount of iodine and 10 ml of tetrahydrofuran under stirring at a temperature in the bulk of 40° to 50° C. in a nitrogen atmosphere to prepare a Grignard reagent. This Grignard reagent was dropwise added to a solution of 4.46 g of 4-bromopyridine and 0.4 g of bis(1,3-diphenylphosphinopropane)nickel (II) chloride in 100 ml of tetrahydrofuran at a room temperature in a nitrogen atmosphere. The obtained mixture was refluxed for 4 hours and allowed to cool to a room temperature, followed by the addition of water. The obtained mixture was distilled to remove the tetrahydrofuran. Ethyl acetate was added to the residue. The obtained mixture was extracted with dilute hydrochloric acid thrice. The extracts were combined, allowed to stand for a short time, made alkaline with concentrated aqueous ammonia and extracted with chloroform. The extract was dried over anhydrous magnesium sulfate and distilled to remove the solvent. The residue was purified by silica gel column chromatography (solvent: chloroform/methanol) to obtain 3.28 g of the title compound as a pale yellow crystal (yield: 64%).

The temperature of the obtained mixture was gradually raised to 0° C. After one hour, ice-water was added to the mixture. The obtained mixture was washed with ether. The pH of the aqueous layer was adjusted with concentrated hydrochloric acid to about 4 to precipitate a solid. This solid was recovered by filtration and washed with water and methanol to obtain 5.44 g of the title compound as a pale yellow powder (yield: 75%).

EXAMPLES OF THE COMPOUND II Manufacturing Example 1 (E)-4-(4-fluorophenyl)-3-butenoic acid ##STR125##

74.4 g of 4-fluorobenzaldehyde and 233.6 g of β-carboxyethyl-triphenyl phosphonium chloride were suspended in 700 ml of tetrahydrofuran and these were incubated on ice and stirred. Into this 500 ml tetrahydrofuran solution of 141.4 g of potassium tert-butoxide was added slowly dropwise. 30 minutes after temperature was brought to room temperature and then they were stirred for 10 hours. After adding thereto ice water and cleaning with ether, the hydrogen-ion concentration of water layer was set to pH2 with undiluted hydrochloric acid. Extraction was then made with ethyl acetate. After drying with magnesium sulfate and concentration made under reduced pressure, the solid obtained was recrystallized from hydrous ethanol, and 53.98 g of marked compound (yield: 50%) was obtained as white needle crystal.
